Answer 1

按照苹果的文档 registerForRemoteNotificationTypes ：在iOS的8已被弃用，而不是你可以使用registerForRemoteNotifications和registerUserNotificationSettings 。

Answer 2

The culprit can be seen in the third line from top

2014-09-17 08:58:00.067 [783:12416] -[NSArrayI numberOfSectionsInTableView:]: unrecognized selector sent to instance 0x7f9250fa9e00
2014-09-17 08:58:00.085 [783:12416] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayI numberOfSectionsInTableView:]: unrecognized selector sent to instance 0x7f9250fa9e00'

Put an exception breakpoint in your code first

Then again run the code and see in which line your exception is getting raised. In your case there seems to be some issue due to which numberOfSectionsInTableView (which is a tableView delegate method) is getting called on an NSArray object.

Try with the exception breakpoint and debug and see. Cheers. Have fun

Answer 3

Your view controller must conform to this protocol UITableViewDataSource : there are two methods witch are @required and these you need to implement in your code:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section;
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;

But there are other methods too. You have to implement numberOfSectionsInTableView:

Take a look if delegate & datasource are linked to viewcontroller in all storyboards or viewcontroller .m class

If this is still not the problem. Try with breakpoints and debug the problem...
